PRINTING-PRESS.

Specification of Letters Patent.

Patented Sept. 4, 1917.

Application filed July 29, 1916. Serial No. 111,999.

To all whom it may concern:

Be it known that I, WILLIAM J. RAM- SAIER, a citizen of the UnitedStates, and resident of the borough of Manhattan, city, county, andState of New York, have invented certain new and useful Improvements inPrintin '-Presses,of which the following is a specification.

This invention relates to improvements in that class of printing pressesin which the type or printing surface is held on a bed and the printingplaten is carried by a rocking bridge. The inking rollers are mounted ina carriage which is normally at the top of the type bed and is moveddown across the face of the printing surface and back to its normalposition while the bridge and the printing platen are moved away fromthe type bed. This type of press is generally known as the universalplaten printing press. The invention is applicable to any form of presswith a rocker bridge and a printing platen carried thereby.

One of the main objects of this invention is to simplify and improve themeans whereby the inking roller carriage will be actuated from theplaten-carrying bridge, or the mechanism connected to and operatingtherewith.

Another object of the invention is to provide means whereby the inkingroller carriage actuating mechanism may be disconnected from theplaten-carrying bridge through the operation of the throw-off bar.

Another object of the invention is to pro vide means whereby when thethrow-off bar is returned to its normal position, the inking rollercarriage will be again connected to its actuating mechanism.

There are other important objects and advantages of the invention whichwill fully hereinafter appear.-

In the drawings, Figure 1 is a vertical sectional view of the press, theinking roller carriage and the printing platen being shown in sideelevation;

Fig. 7 a detail side elevation of the means for disconnecting the inkingroller carriage mechanism from the actuating mechanism connected to therocking bridge; and

Fig. 8 a detail rear view of the mechanism shown inFig. 7;

Referring to the various parts by numerals, l designates the maindriving shaft which may be rotated in any suitable manner and from anysuitable source of power. On this shaft is secured a disk 2 whichcarries a crank pin 3. On this pin is mounted the rear end of aforwardly extending bridgevoperating link 4. The shaft 1 carries asecond disk similar to disk 2, and to this disk is connected anotherlink 4, the forward ends of said links being connected to the oppositeends of theplaten-carrying bridge 5.

The platen-carrying bridge is formed with curved rockers 6 which bear onhorizontal tracks 7 located in the forward up per part of the machineframe. The bridge is formed with forwardly and downwardly extending sideplates 8 which carry, at their forward ends, inwardly extending lugs 9,said lugs bein adapted to engage and slide on the tracks T when theprinting platen is completing its inward printing movement. The printingplaten 10 is supported at the inner side of the bridge and is adapted tobe brought into close proximity with the forward face of the type bed11, as shown in Fig. 1, when the bridge is at the end of its inwardmovement. The bridge is guided in its rocking movement by the slottedcam guide 5*, as shown clearly in Fig. 1 and as is well known in thisclass of presses. When the bridge has beenmoved forwardly a sufficientdistance to free the lugs 9 from the tracks 7, the bridge will be rockedforwardly and downwardly, bringing the printing platen to an inclinedposition and permitting the removal of the printed sheet and the properadjustment of the new sheet to be printed.

The cam guide 5 carries a downwardly extending bracket 12, said cam andbracket trio being formed with a forwardly extend-v V tendingsubstantially horizontal arm 15.

On the eccentric is mounted a sleeve 16 to 1 which is rigidly connecteda downwardly extending operating bar 17. Pivoted on a horlzontal bar 18is a bell crank lever 19, one arm of which extends forwardly anddownwardly and is connected to the lower end of the bar 17, the otherarm extending upwardly and forwardly and being connected at its upperend to the upwardly and irearwardly extending operating-hook 20. It isobvious from the foregoing that as the bridge is rocked forwardly anddownwardly, the bar 17 will be-raised and the operating-hook thrownupwardly and ream wardly by means of the lever 19; and upon the reversemotion of the rocking bridge the operating-hook will be drawn forwardlyand downwardlv.

At the rear of the machine, above the rear end of the operating-hook, ismounted a transverse rock shaft 21. To the ends of this rock shaft aresecured upwardly and forwardly extending crank arms 22, whose upperends'are connected by links 23'to the roller carriage 24. The rock shaft21 is alsop-rovided with two short, downwardly and forwardly extendingarms 25, said arms being placed a suitable distance on each side of themiddle of said shaft, as shown clearly in Figs. 3 and 8. The lower endsof these arms are connected by a pin 26, on which are mounted threerollers 27, 27 and 28, the locking roller 28 being located between thetwo supporting rollers 27 and 27*, as shown clearly in Fig. 8. Theoperating hook 20 is formed with a slot 29 which runs, for a portion ofits length, substantially parallel with the longitudinal line of thesaid hook. Near its rear end this slot is inclined downwardly andrearwardly, and at the forward end of this inclined portion an upwardlyextending portion 30 is formed, said portion 30 being substantiallyperpendicular to the main body of the slot, as shown clearly in Figs. 1and 7. The locking roller 28, in the normal operation of the machine,rests in the portion 30 of the 'slot of the operating hook, as shownclearly in Fig. l, the parts then being in their normal locked andoperative position. It is manifest that as the operating-hook isreciprocated, the rock shaft 21 will be rotated and the inking rollercarriage moved down over the printing surface and then back to itsnormal position above the platen.

Whenever it may be desired to disconnect the operating-hook from theinking roller carriage it is only necessary to lift the operating hook20 sufficiently to release the locking roller '28 from the portion 30 ofthe slot of the operating-hook. For this purpose I provide the followingmechanism, and adapt the same to be operated from the platen throw-offbar.

The throw-off bar 31 is mounted on the upper. ends of arms 32, said armsbeing connectedto and extending radially from eccentric sleeves 33 whichsurround the bridge trunnions 34, as is usual in presses of this type.Rigidly connected to the throw-01f bar and extending downwardlytherefrom, is an arm 35, said arm being curveduaround the forward curvedside of the platen-carrying bridge, as shown clearly in Fig. 1. To thelower end of this arm 35 is connected a link 36, the lower end of whichis connected tolthe forward end of the arm 15. e As heretoforedescribed, the arm 15 is connected to the eccentric sleeve 14 mountedonthe pin 13. By thus con necting the throw-off bar to the eccentricsleeve 14 the variation in the distance between the center oftllQtIHIlTllOIlS 34 and the center of the pivot'17 at the lower end ofthe operating bar when the throw-off is operated, is automaticallycompensated for. When the throw-off bar is moved forwardly anddownwardly the bridge is moved forwardly through the eccentric sleeves33. Thisslightly increases the distance between the centerof the pivot17*" and the center of the trunnions 34, and this slight increase indistance must be compensated for in order to prevent a partial operationof the inking roller carriage. As the movements of this carriage and allof its operating mechanism are carefully timed,jit is essential that theproper operative relations be maintained when the throw-off bar isoperated. The throw-off bar is released by means of the cams 37 saidcams being operated through the bar 38 as is usual in devices of thiskind. V

Mounted on the operating bar 17 is a sliding head 39- The bar 17 isformed with two slots 40, and in said slots are mounted blocks 41, saidblocks being connected to the sliding head by means of transverse pins42, so that thehead will be accurately guided in its vertical movement.Connected to the sliding head is a; link 43, the up per end of which isconnected to the forwardly extending arm 15 of the sleeve 14, wherebythe sliding'head will be vertically reciprocated throughthe operation ofthe throw-off bar. On one side of the sliding head is formed an inclinedcam 44, said cam extending upwardly and forwardly from the rear edge ofthe head. On the opposite side of the sliding head isformed a cam 45,said cam extending downwardly and forwardly fromithe rear edge of thesliding head, as indicated clearlyin Figs. 1 and 5 of the drawings.These cams 44 and 45 are point above its adapted to engage the forwardends of horizontally movable bars 46 and 47, cam 44 being adapted toengage bar 46, and cam 45 being adapted to engage bar 47. The forwardends of these bars are provided with suitable antifrictio'n rollers, asindicated in Fig. 1; and said bars are mounted to slide in a bearing 48in the machine frame. At the rear of the machine frame, below theoperating hook, is mounted a transverse bearing rod 49, and on this rodis pivotally mounted a hook-releasing device 50. This device is formedwith two upwardly extending arms 51, between which fits theoperating-hook 20, as shown clearly in Fig. 8. A lifting roller 52 ismounted between said arms 51 and is adapted to engage the lower edge ofthe operatinghook and lift it sufliciently to free the locking roller 28from the portion 30 of the slot 29 in said hook; On the upper ends ofthe arms 51 are formed curved supporting flanges 53,

which are adapted to fit under and engage the supporting rollers 27 and27 when the operating-hook has been released from the roller 28, asshown clearly in Fig. 7. When the parts are in this position the entireweight of the inking roller carriage andits operating parts is supportedthrough the arms 51, the cross bar 49 and the machine frame. It ismanifest, therefore, that it will be unnecessary to provide anycounterbalancing weight to support the inking roller carriage when saidcarriage operating mechanism is disconnected from the rocking bridge.The rear end of the bar 46 is connected to the releasing device belowthe pivot thereof, and the rear end of the bar 47 is connected to thereleasing device at a pivot, as shown clearly in Figs. 1. and 8 of thedrawings.

As shown in Fig. 1 of the drawings, the bar 47 is adapted to be engagedby the cam 45 when the sliding head 39 is moved downwardly through theaction ofthe throw-off bar. The rearward movement of the bar 47 throwsupwardly the releasing device, thereby elevating the rear end of theoperatin hook and bringing the rollers 27 and 2? to rest on the flanges53, thereby disconnecting the inking roller carriage from the'opcratingmechanism. It is manifest that as the bar 47 is moved rearwardly the bar46 will be thrown forwardly into the path of its actuating cam 44, sothat when the slid: ing head is elevated by the return of the throw-offbar to its normal position said bar 46 will be engaged by its cam 44 andforced rearwardly. This operation will move the releasing device forwardand permit the hook to drop and bring the portion 30 of the slot 29 inposition to receive the roller 28. It is manifest from the foregoingthat the inking roller carriage will be rendered inoperative when thethrow-off bar is moved forwardly and downwardly; and that it will beautomatically rendered operative when the throwbfi bar is moved back toits normal position. The mechanism for releasing the operating-hook fromthe locking roller 28 and for permitting the operating-hook to drop intoengagement with said locking roller, constitut 5 what might be properlytermed a make-andbreak device in the mechanism for operating the inkingroller carriage, that is to say, these devices form means by which thesaid mechanism may be renderedoperative or inoperative by making orbreaking the operative connection be tween the bridge and the inkingroller carriage.

It is frequently desirable to maintain the inking roller carriageoperatively connected to the rocking bridge when the throw-off bar hasbeen operated, in order that the ink may be rolled a number of timesover the printing surface before an impression is taken. To accomplishthis I secure the cam 45 on a plate 54, said plate being pivoted at 55on the sliding head and formed with aloosening the clamping nut 57 theplate 54 may he moved downwardly, thereby withdrawing the cam 45 fromthe path of the arm 47. In this position of the parts the bars 46 and47' will not be operated during the vertical reciprocation of thesliding head 39, and therefore the releasing device will remain inactiveand the operating-hook will remain in operative connection with theroller 28. The plate 54, when released, will be dropped down to a stoppin 57 on the sliding head.

The inking roller carriage shown in Fig. 1, forms the subject-matter ofanother application for Letters Patent, and will not, therefore, bedescribed herein.
